What is the Correlation of your Trading Strategy and the Market?

Market Correlation is a topic that’s been covered extensively before this post. The correlation between assets within an asset class or even the correlation between trading strategies themselves. Correlation can take many forms.

Darwinex created an Investible Attribute called, you guessed it, Market Correlation. This Investible Attribute doesn’t measure the correlation between strategies or assets.

Instead, it measures the correlation of the Strategy and the underlying market.

Intrigued? Thought you might be.

Suppose the performance of your trading strategy starts to decay. In that case, the higher-level performance metrics mentioned in the previous posts do little to ascertain the route cause for the change in performance.

SQN, D-Score, Sharpe ratio can all tell you how well a strategy is doing. However, what they can’t do is tell you what part of the Strategy is causing a decrease in performance.

The SQN won’t tell you if your entry timing is less effective or if your position sizing is too high, causing increased drawdown. To do this, you need metrics that focus on the key aspects of a trading strategy.

That’s where Darwinexs’ Investible Attributes come in.

Because Darwinex realised that being able to rank various factors of a trading strategy is invaluable for Investors, they created 12 Investible Attributes. Traders can also use these Investible Attributes to analyse the underlying Strategy itself.

The Market Correlation Investible Attribute looks at the correlation between the underlying market and the trading strategy itself. It then ranks how much value the trader is providing.

Let’s explain in more detail.

Let’s say a trader has a long-only stock portfolio. The trader enters longs and then does nothing but sit and wait to see what the market does. If the market is bullish, the stocks go up, and the trading strategy does well.

However, if the market falls, the trading strategy loses money. This scenario would return a low Market Correlation score. The positive or negative return isn’t due to the trading strategy. It’s due to the underlying market being bullish or bearish.

Alternatively, let’s say the trader only longs the same stocks for 3 hours a day at London open. If the stock market declines overall, but the London session tends to open bullish, and the trader can capture these positive returns but avoid the fall of the market overall, the operational decisions of the trader are providing value to investors.

The trader is making decisions to try and outperform the underlying market. This results in the trading strategy having a higher Market Correlation score due to the trader not relying on the directional bias of the underlying market.

(Mc) measures the Correlation of the Strategy with the underlying market. How do you measure the risk of an underlying strategy?

Risk, in general, is a broad topic. There are lots of different types of risk. One of them is associated with the stability of the underlying Strategy, and this is where the Risk Stability investible Attribute excels.

Because the Risk Stability Investible Attribute ranks the consistency of the underlying trading strategy. A low (Rs) score would indicate that the underlying trading strategy has an unpredictable risk profile. Why does this matter?

If a trading strategy has inconsistent trade exposures, this can negatively affect the return distribution. What happens if a higher majority of losing trades have a more significant exposure?

You could have a potentially winning strategy that loses money. This concept was covered in the post about Van Tharp’s R multiples.

By equalising the risk of each trade, you increase the Risk engines ability to stabilise the risk for Investors.

This is a much more robust way of approaching how to size your trades.

Furthermore, a low (Rs) score combined with another Investible Attribute can indicate potentially dangerous trading behaviour. More on this in a future post

Did you know?

Darwinex created a stand-alone risk engine to actively manage the risk of a DARWIN independently of a DARWIN provider (Trader). It is this risk engine, amongst other things, that enables DARWINs to charge performance fees that are paid to the DARWIN Provider.
